The length of a rectangle is four times the width minus three. If the perimeter of the rectangle is 64 meters, what is the length?

Answers

Answer:

L = 25 m

Step-by-step explanation:

L = 4W - 3

perimeter = 2(L + W)

64 = 2(4W - 3 + W)

divide both sides by 2:

32 = 5W - 3

add 3 to each side:

5W = 35

divide both sides by 5:

W =7

L = 4(7) - 3 = 25

Aaron and two friends went to the movies and spent a
total of $33. The group bought a box of popcorn to
share that cost $ 6. What was the cost of each movie
ticket?

Answers

Answer:

6 + (t x 2) = 33

T = Ticket Cost

6 - 6 + (t x 2) = 33 - 6

t x 2 = 27

t x 2/2 = 27/2

t = 13.5

Each ticket cost 13.50$

Compose an expression that can model the first three terms of any arithmetic sequence in terms of just a and d. Type your answers in the most simplified form.

Answers

Answer:

First term: a

Second term: a+d

Third term:a+2d

Step-by-step explanation:

An expression that can model the first three terms of any arithmetic sequence in terms of just a and d is aₙ = a + (n - 1)d.

What is an arithmetic sequence?

An ordered group of numbers with a shared difference between each succeeding term is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 8, 13, 18, and 23 is 5. An arithmetic progression is another name for an arithmetic sequence.

How to solve this problem?

Let the a be the initial term of a sequence and d be the common difference, then the nth term of any arithmetic sequence can be written as aₙ = a + (n - 1)d.

If we want first three terms of any arithmetic sequence, then we have to put n = 1, 2, 3 in the above expression.

So, for n = 1, a₁ = a + (1 - 1)d = a + 0d = a

for n = 2, a₂ = a + (2 - 1)d = a + d

for n = 3, a₃ = a + (3 - 1)d = a + 2d

Therefore, an expression that can model the first three terms of any arithmetic sequence in terms of just a and d is aₙ = a + (n - 1)d.

Can someone edit this. It is supposed to be like 2 paragraphs and about the nullification crisis As of right now, according to Oregons Law ...anyone under the age of 16 operating an ATV on public lands is to be supervised by an adult over the age of 18Youth under the age of 16 are required to have on-line safety training and hands-on rider training. While Federal laws state ...to be at least 12 years of age to operate an ATV on state land. When you look at the rates, it shows the only of the fatalities are riders who are 16 and under. That leaves the other to be LEGAL adults. Meaning in places like Oregon who have less riders than states such as Idaho should minimize the legal age down to at least 14. That way both sides would still get what they want. Oregon will have the age higher than Federal laws and Federal will have it lower than what Oregon wants it to be. I do believe that they should nullify this law because quite a bit of Oregon doesnt ride so the fatality rate would stay down. I am bringing up the fatalities because that is the only reason that Oregon's Law still is to be 16 and older. It would be a little different if the was younger riders. I do believe that states should be able nullify certain laws. Many laws vary depending on the person. But people vary from state to state. So each state is different and needs different laws.
